13 Claims.

My invention relates to improvements in coal chutes. It has for one object to provide a new and improved form of coal chute particularly forv use in connection with locomotive fueling stations wherein the gate which controls the flow of coal will not jam, will not permit unauthorized or unintended leakage of coal, will insure a uniform fiow of coal from the bin while preventing skimming or control of the character of coal by chutefmanipulation. Other objects will appear from time to time throughout the specification and claims.

My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein- I Figure 1 is a side elevation in part section;

Figure 2 is a section along the line 2-2 of Figure 1;

Figure 3 is a side elevation on an enlarged scale of the gate and associated parts;

Figure 4 is a section through the gate and associated parts parallel to the View shown in Figure 3;

Figure 5 is a section along the line 5--5 of Figure 3;

Figure 6 is a front elevation of the gate in the closed position;

Figure 7 is a section along the line of Figure 3.

Like parts are indicated by like characters throughout the specification and drawings.

I is a coal bin having an inclined bottom wall 2', a vertical front wall 3, there being an aperture or port 4 in the front wall immediately adjacent the lower extremity of the inclined bin. This aperture4 is encircled by an angle flange 5 to which is bolted a fixed gate chute 6 which is rectangular in cross section, the lower floor of which is in general alignment with the floor 2. 1, l are brackets on the upper wall of the fixed chute. 8 is a rock shaft rotatable in those brackets. 9, 9 aresleeves bolted to the opposed ends of the rock shafts having lugs ID to which arebolted control levers H from which depend downwardly operating rods l2, from which the engineer or fireman in the tender may open or Cit IS on the side walls of the fixed chute. The link [5 is pivoted to a lug 20 on each of said inturned ends so that the link I5 causes rotary movement of the upper gate portion l8 about its pivot point. The upper gate arcuate portion l8 has a straight cutting edge extending clear across the chute. The lower gate member comprises two superposed arcuate gate sections 2|, 22, section 2| being reinforced by 22 and both being supported on a stirrup 23 having stirrup arms also pivoted at [9. The link 14 pivoted to a lug 24 causes operation of this stirrup member. Reference to Figure 6 shows that the undercut portion does not have a straight cutting lip but tapers upwardly to a point at the center.

Figure 3 shows the parts in the closed position. Figure 4 shows the parts in the open position. A counter clockwise rotation of the rock shaft 8 first takes place without movement of the gate l8 because the pin ll slides in the slot l6 and cushions the opening movement of the lower gate section. Later on as the excursion proceeds to the position shown in Figure 4 both gates are opened. On the return or closing movement clockwise direction of the rock shaft 8 immediately causes a forward or closing movement of the lower gate but the closing movement of the upper gate does not start until the pin IT has returned from the position of Figure 4 in the right hand end of the slot to the position of Figure 3 in the left hand end of the slot.

The result of this is that in order to open the gate, the operator must manipulate the rock shaft to first start the withdrawal of the lower pointed gate member and then to finish with the completion of its withdrawal and the opening of the upper straight edged gate portion. This results in a full flow of coal. As the gate closes, the upper gate portion remains at rest until the pointed gate portion has come partially into play tending to divide the flow of coal and tending as the two gates come together to gradually restrict the passage up to a point where the pointed gate is immediately adjacent the upper gate when coal flows through two passages, one at either side of the chute. Therefore coal movement is entirely stopped. This arrangement insures that a uniform fiow of coal will take place.

Depending downwardly from the pivot pins i9 on the fixed chute is a yoke 25 which yoke extends across beneath the fixed chute. 26 is an adjustable chute pivoted on the yoke. This adjustable chute extends upwardly behind and above the lower extremity of the fixed chute and has at its end a boot 2! adapted to catch and guide the coal. 28 is a ring associated with the boot which may be grasped by a hook 29 in the hands of the operator to pull the adjustable chute down from the position shown in dottedlines in Figure l to the position shown in full lines. 30 is a bail to which is fastened a holding rope 3! which extends up to any suitable counterbalance. Figure 2 shows the angle of movement possible for this adjustable chute whereby the coal may be properly positioned on the tender of the locomotive.

32 is a flange extending across the upper outside wall of the chute adapted to limit the upward movement of the gate i8. Welded to the flange 32 and extending downwardly on both sides of the chute are channelled bearing members 33 for the pivot pins Hi.

I claim:
